Sealed Window Constructions, of which the following is a specification.

My invention relates to windows, and;

0 particularly to windows of the general type shown in Patent No. 1,241,090 dated September 25, 1917, in which the jambs have vertical slots in their inner faces and enlarged openings behind such slots and the '15 sashes have plates which extend into such slots.

With windows ofthis type I have heretofore found it highly desirable to provide means for adjustin the sizeof-the slots in order to make a tig t joint between the sash plates and the edges of the slots. I have now found that this necessity of adjustment can be done away with if spring means are provided for taking up the clearance between the sash plates and the slot edges so that the sash plates are at all times held against one slot edge. I have also found that the most advantageous way of arranging such spring pressure is to provide a metal plate of springy material, such, for example, as spring brass which is eitherat tached to the jamb (preferably inside the jamb) and presses the sash plate against one edge of the slot or is attached to the sash 85 in such a way that such spring plate presses against one edge of the slot and presses the sash plate against the other edge of the slot. In either case it is highly desirable to have the spring plate mounted a substantial distance from the point at which the pressure is exerted, so that the plate can flex easily to prevent binding 'when the window is opened, and it is also desirable that the plate be mounted in such a way that air cannot pass between the sash plate and the slot edge from which the corresponding sash plate is pressed, and thence around the outer edge of the sash plate.

The'way in which my invention can be carried out will be readily understood from the illustrative examples shown in the accompanying drawings, in which Fi .'1 is a sectional view of a-construction in w 1011 the spring plates are attached to the sashes, and Fig. 2 is a corresponding sectional View showing an arrangement in which the spring plates are attached to the iambs.

Referring to the drawings, 2 is a portion of the inner face of the jamb; 3 is a baflie member likewise forming a portion of the inner face of the jamb and 1- is a hook shaped member which forms the balance of v each sash a spring member 9 which may be madeof spring brass or other metal as desired which extendsthe height of the sash to which it is attached and is so shaped that it can be hooked around its corresponding member 7 or 8, where it will be held in place by the glass '10. The free end of each memher 9 is sprung outwardly and extends a short distance through the appropriate slot 5 or 6. By this arrangement plate 7 is held pressed against member 2 and plate .8 is held pressed against member 3 and the passage of air between. member 3 and plate'7 or between member 4 andflplate 8 is prevented by spring member 9.

Referring to Fig. 2.which shows a similar construction with a reversal of parts, I pr0- videfor the outer sashplate 8 a spring member 11 which, as is shown, is bolted to the outer portionof member 4 and is bent then toward the rear of the window and again inwardly, so that there is provided a rubbing surface substantially parallel to the sash plate 8 which will rub against the sash plate adjacent to the edge of member 4.

In like manner I provide a spring member 12 which is attached to member 4 by having its end beneath baflle 3 and then, is

bent in a manner corresponding to that described in connection with member 11 so that it will press against plate 7. With the construction shown in Fig. 2 any air that may pass between spring plate 11 and momher 4 or between spring plate 12 and member 3 will be prevented from passing round the outer edge of plate 8 or plate 7.

Those skilled in the art will readily understand that these spring members may be arranged in many different ways, audit is to be understood that the illustrative examples given can be modified in many particulars without departing from the spirit of my invention.

hat I claim is: i

1. The combination of jambs having vertical slots in their inner faces and enlarged openings behind such slots,.sashes havlng plates extending through s ch slots into said openings, and adapted 0 make joints between the sashes and the jambs by contact with the edges of the slots, spring means for holding said plates in contact with slot edges to make atight joint When the window is closed, and adapted to yield to permit the sashes to be moved up and down easily, said spring means comprising metal plates of spring metal, each having a rubbing face substantially parallel to the face of a jamb plate positioned adjacent a slot edge, means for mounting said spring plates a substantial distance to one side of said slot in such a way that the discharge of air between the sash plate and the slot edge from which it is pushed by the spring plate and thence around the outer edge of corresponding jamb plate is prevented.

2. The combination of jambs having'vertical slots in their inner faces and enlarged openings behind such slots, sashes having plates extending through such slots into said openings, and adapted to make joints between the sashes and the jambs" by contact with the edges of the slots, spring means for holding said plates in contact with slot edges to make a tight joint when the window is closed, and adapted to yield to permit the sashes to be moved up and down easily, said.

spring means comprising plates carried by the sashes extending substantially the height of the sashes adapted to rub against the slot edge, each of which plates is mounted on the sash a substantial distance from such slot edge.
